Assuming everything has gone to plan, you will see a new item in the lower right hand corner of the status bar. By default it says something like English (United States). This is the main UI component that lets you change dictionaries, disable/enable the spell checker and configure the default languages.

Spell Checking Dictionaries

Clicking on any of the dictionaries will reload them in real-time, no need to restart Brackets. Additionally, the plugin will not load a dictionary unless it actually needs to be used. A good example is if both the American and British English dictionaries are specified to load in a user profile, the extension will check the first dictionary, and if the word is spelled correctly it won't consult the second dictionary. Only when a word is flagged as misspelled by one dictionary will the extension start checking in other dictionaries.

Error Visualizations

The following image shows what it looks like when there are spelling errors. You can also right click on incorrect word to view suggestions and replace the word. There is currently no feature to add to dictionaries through the UI.

it is important to note that the spell checker will attempt to spell check your source code. It will even spell check the various words that make up a camelCased variable name. Give it a try, and if it is too much in your code you can disable it from the UI when working on source code.
